Legal information
Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by personnel qualified for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.

Note
•
Pointek CLS200/300 is available in two models: the standard model, and the digital model
with integral local display. For information on the CLS200/300 Standard, please see
manual 7ML19985JH02.
•
Pointek CLS200/300 is to be used only in the manner outlined in this instruction manual,
otherwise protection provided by the equipment may be impaired.
•
This product is intended for use in industrial areas. Operation of this equipment in a
residential area may cause interference to several frequency-based communications.
Pointek CLS200/300 is a versatile capacitance switch, ideal for level detection of interfaces,
solids, liquids, slurries, and foam, and for simple pump control. The switch responds to the
presence of any material with a relative dielectric constant of 1.5 or more by detecting a
change in capacitance, which is registered as a change in oscillating frequency.
The switch can be set to detect before contact or on contact with the probe. The design of
the CLS200 Digital allows the instrument to operate independently of the tank wall or pipe,
so it does not require an external reference electrode for level detection in a nonconductive
vessel such as concrete or plastic1). The CLS300 Digital requires a connection to earth/ground
for effective capacitance measurement.
The power supply is galvanically isolated and can accept voltages in the range 12 to 30 V DC
(12 to 24 V DC for Intrinsically Safe (IS) models), depending on the application. The materials
used in the probe construction provide a high level of chemical resistance, and an excellent
temperature rating on the process wetted portion of the probe: up to 125 °C (257 °F) for the
CLS200 and 400 °C (752 °F) for the CLS300.
Modular design and construction provide a wide choice of configurations, including rod,
cable, and sanitary versions. Pointek CLS200/300 Digital can be used either:
•as a standalone unit, programmed locally using the local user interface, or
•installed as part of a network, programmed remotely using SIMATIC PDM on a Profibus PA
network (or locally using the Local User Interface).

4.1 Pointek CLS200/300 applications
Pointek CLS200/300 is designed for level detection and simple pump control in a variety of
applications:
•Liquids, solids (powder and granules), slurries, interface detection (for example, oil/
water), and foam detection
•Foods and pharmaceuticals
•Chemical and petrochemical
•High pressure and temperature
4.2 Alarm signalling
Alarm signalling
The solid-state switch can be set to react either to a diagnosed fault in the instrument, or to a
change in the process level.
Fault Signalling
Pointek CLS200/300 can actively report information on its own status via PROFIBUS PA when
used as part of a network, or by means of a pre-defined output status at the solid-state switch
and on the Local User Interface (LUI).

5.1.3.2 Mounting
Pointek CLS200 (compact threaded probe shown)
High level alarm
Low level alarm
①Normal process level
②Vertical
③Normal process level
④Horizontal
For high level alarm (level exceeds normal process level):
•normally mounted into the vessel top, or
•mounted through the tank wall at the detection level
For low level alarm (level drops below normal process level):
•mounted through the tank wall at the detection level
Pointek CLS200 typical configuration with extensions:
High level alarm
Low level alarm
①Normal process level
For high or low level alarm:
•designed for top mounting. The probe suspends vertically so that it reaches into the
process at the desired detection level (high or low detection alarm).
